Classroom usual performance depends primarily on the height of the rate of attendance of teacher's roll-call statistics.In student, roll-call process is dry as dust,
It wastes time.And it is putd question in existing tutor auxiliary platform equipment without presenting to call the roll at random in classroom, and according to student's
Answer the function that situation carries out scoring and cumulative statistics.
Summary of the invention
To solve the above problems, the present invention provides a kind of classroom questioning and scoring system based on dual random algorithm.
By the speaking ability by random question of system, changes the mode that traditional teacher's roll-call is putd question to, give student's feeling of freshness；And it can will answer a question
As a result quantified, keep usual performance more transparent, it is just.
To achieve the above object, the technical solution of the speaking ability by random question system for classroom instruction of the invention are as follows: information record
Enter module, information deletion module, speaking ability by random question module, score statistical module, database module.
Data input module, the module can be with typing curriculum information, class's information, the in the class name of all students and
Number.
Information deletion module is for deleting outdated information.
Speaking ability by random question module, to guarantee that randomness, the present invention devise dual random algorithm, student's student number and name pressed
After student number sequence reads in array, array is upset in situ using random algorithm at random first, is once shuffled；Then again
1, which is obtained, using random function obtains phase using the integer as the index of array to an integer between N (student's quantity)
The student information for answering array element to store, puts question to the student.
Score statistical module, student can obtain corresponding classroom usual performance after answering a question every time, according to problem
Score is set as 0-5 points by complexity.Teacher can take the circumstances into consideration to give a mark according to the complexity of problem and the answer situation of student,
Best result 5 divides, and minimum point 0 point.Term end can be by the accumulative addition of achievement of answering a question of each student, and final result publicity is to
It is raw, to show that teacher's justice discloses just working attitude.
Database module, for saving all information of this system, including curriculum information, class's information, student information and
Score information, other modules obtain or delete relevant information by interacting with the module.
The invention has the benefit that randomly select the student being asked by system, break traditional teacher call the roll or
The mode that point student number is putd question to makes student to puing question to link to be filled with curious sense, and expectation is seen puts question to whom can be by system " good fortune every time
Fortune " extract, reduce the influence of the subjective emotion factor of teacher asking questions, due to each classmate have be selected answer a question can
Can, in order to which the roll-call one by one for counting the rate of attendance is no longer necessary, save the time；Meanwhile teacher can returning every time according to student
It answers situation and provides classroom usual performance, problem is 0-5 points according to the horizontal score value of difficulty or ease and differs, and in term and term end is by classroom
Usual performance carries out quantitative statistics, in case teacher only provides usual performance with subjective impression.
